The carbonyl clusters [Fe-3(mu(3)-Q)(mu(3)-AsR)(CO)(9)] (Q = Se and Te; R = meta- and para-HOOCC6H4) were obtained from the salts K-2[Fe-3(mu(3)-Q)(CO)(9)] and organoarsenic diiodides RAsI2 prepared by reducing iodination of arsonic acids RAsO(OH)(2) according to a novel method. The structures of the clusters were identified by X-ray diffraction. The crystal packing motifs of the dimers of the cluster molecules and their relationship with the solubility of the clusters are discussed. The sequential steps of the thermolysis (decarbonylation, decarboxylation, and decomposition of the organic fragment) of the clusters were studied. The presence and location of the carboxyl group does not influence the decarbonylation temperature.
